I just updated tot he latest mac version. But now the app crashes at startup. It displays a popup saying that the skydrive folder cannot be found (but its in the same place that its always been! With all the documents fully accesible) and that app should be restarted, with an option to restart right there on the popup. But it only displays for a few seconds (without time to press the 'restart' button), and crashes.
Trying to restart the app yields the same results. (Mac OS 10.7.5)
But again, it was running just fine before the most recent update a few days ago. It started this behaviour after I tried logging back in for the first time after the update.

I have repeatedly tried uninstall/reboot/reinstall afresh, with no luck.
